Codeigniter parentheses in dynamic Active Record query

Question

I\'m producing a query like the following using ActiveRecord

SELECT * FROM (`foods`) WHERE `type` = \'fruits\' AND 
       `tags` LIKE \'%green%\' OR `tags`          


        

Answer 1

use codeigniter 3

$this->db->select('*');
    $this->db->from($this->MasterMember);
    $this->db->group_start();
    $this->db->where($this->IDCardStatus, '1');
    $this->db->or_where($this->IDCardStatus, '2');
    $this->db->group_end();

    if ($searchKey1 != null) {
        $this->db->group_start();
        $this->db->like($this->MemberID, $searchKey1);
        $this->db->or_like($this->FirstName, $searchKey2);
        $this->db->or_like($this->LastName, $searchKey3);
        $this->db->group_end();
    }

    $this->db->limit($limit, $offset);


    $data = $this->db->get();

this is my native query

SELECT
    * 
FROM
    `Member` 
WHERE ( `Member`.`IDCardStatus` = '1' OR `Member`.`IDCardStatus` = '2' ) 
AND ( `Member`.`MemberID` LIKE '%some_key%' ESCAPE '!' OR `Member`.`FirstName` LIKE '%some_key%' ESCAPE '!' OR `Member`.`LastName` LIKE '%some_key%' ESCAPE '!' ) 
    LIMIT 10
